Abstract (en)

[origin: US2019123240A1] A method of manufacturing a light emitting diode (LED) is provided. The method includes forming an n-type semiconductor layer on a substrate, forming an n-type electrode in a first region of the n-type semiconductor layer, forming an active layer in a second region of the n-type semiconductor layer, the second region being a region other than the first region, forming a p-type semiconductor layer on the active layer, and forming a resistance layer by etching regions of the active layer and the p-type semiconductor layer.
